Explain the principle of the following physical experiment about magnetism.
Magnetic perpetual motion machine is another name for magnetic motive. Its working principle is the mechanical movement caused by the principle that the two poles of a permanent magnet (South (S) and North (N) are repulsed by the same name or attracted by different names. But magnetic motive is also based on the theory of conservation of energy, and has not divorced from the laws of physics. This type of perpetual motion machine is not a machine that can move forever.
